"Even the hunter must one day face the sea."
Lieutenant Commander Valentina Solis of the Royal Spanish Navy has spent twelve years hunting pirates across the Caribbean, earning the nickname "La Sombra." When her ship is destroyed by a supernatural armada bearing no flag, she washes ashore in Tortuga — hunted, penniless, and stripped of rank. To survive and uncover who commands the phantom fleet, she must forge an uneasy alliance with the rogues and outlaws she once pursued. As loyalties fracture and the supernatural encroaches on the living world, Valentina discovers the armada's commodore may be the ghost of her own mentor — and the only way to stop him is to become a pirate herself.
